T-s (entropy vs. temperature) diagram of an isentropic process, which is a vertical line segment The entropy of a given mass does not change during a process that is internally reversible and adiabatic. A process during which the entropy remains constant is called an isentropic process, written or . [13] Some examples of theoretically isentropic thermodynamic devices are pumps, gas.. A physical example of this process is illustrated below, in addition to the PV diagram and the Energy-Interaction diagram that describes this particular process. Figure 4.4.3: Example of an Isochoric Process. Using both the 1 st Law and the Ideal Gas Law for an isochoric process, we find that heat depend on the change in pressure as:

This process is an isentropic expansion process and can be represented by an expansion line on the PV diagram. The Condenser Process: The condenser process is where the low-pressure steam leaving the turbine is condensed back into water. In this process, heat is transferred from the steam to a coolant, usually water, in a heat exchanger.. An isentropic process appears as a vertical line on a T-s diagram. The area under a process curve on a T-s diagram is related to the amount of heat transferred to the gas.
